Regarding your customizations - I assume that you have configured the ToolsFile.xml(ListToolsFile.xml) and ConfigFile.xml(ListConfigFile.xml). You can copy and use them with the new version of the control, just remove the enabled and dockingZone attributes from the ToolsFile.xml(ListToolsFile.xml).

If you still experience problem achieving the desired behavior please open a support ticket and send us you customized files. We will check them and do our best to provide a solution
